My favorite from this album too! Maybe because it is oft kicked to the side, it makes it a rare treat to hear live (like Scotty, i was also fortunate in 2004).
Its an awkward song that takes some time to wrap your hands around, which is completely why I love listening to DT. Sometimes prog is a two way street wherein the listener must actively participate in slowly digesting the elements of a song. Thus, I appreciate it all the more.
